Disclaimer: I buy children's books for their illustrations, not the story. I don't just buy a book for it's content, I judge it by it's cover. Usually publishers but its best illustration of the series on the cover. If the cover doesn't do anything for you, you'll likely not like many of the other ones.

I would buy any number of books by this Illustrator. Oh, I already have. He is fantastic! You can't go wrong with a beautiful book of his.
